ABSTRACT:
An ignition system for use with an ignition coil and a source of alternating distributor pickup signals within an internal combustion engine. The system includes a zero crossing detector responsive to the distributor pickup signals and operative to generate a first timing signal, a complex ramp generator responsive to the first timing signal and operative to generate a second timing signal, a gate responsive to the first and second timing signals and operative to generate a constant ignition coil control signal over the normal operating range of the engine, and an output amplifier responsive to the control signal and operative to control charging and discharging of the ignition coil. A voltage control circuit is employed to switch the output amplifier on when the voltage at the ignition coil exceeds a predetermined value.
